A lawyer shall not accept or continue employment when the lawyer knows or reasonably
should know that the person who seeks the lawyers services does so as a result of
conduct prohibited by these rules.

Comment Rule 7.06

Selection of a lawyer by a client often is a result of the advice and recommendation of
third partiesrelatives, friends, acquaintances, business associates and other
lawyers. Although that method of referral is perfectly legitimate, the client is best
served if the recommendation is disinterested and informed. All lawyers must guard against
creating situations where referral from others is the consequence of some form of
prohibited compensation or from some form of false or misleading communication, or by
virtue of some other violation of these rules. This prohibition on accepting or continuing
employment applies even if the lawyer whose services are involved had no direct or
indirect involvement with the underlying violation of these Rules, provided that lawyer
knows of the violation. See also Rule 7.03 (d), forbidding a
lawyer to charge or collect a fee where the misconduct involves violations of Rule 7.03
(a), (b), or (c).
